The Claim

Among patients with coronary artery disease, achieving an LDL-C level below 55 mg/dL does not significantly reduce the risk of major adverse cardiac events in those without lipid-rich plaques (maxLCBI4mm <324.7), indicating that the benefit of intensive lipid-lowering is limited to patients with this specific plaque phenotype.

In plain English

In patients with coronary artery disease, lowering LDL cholesterol below 55 mg/dL does not reduce the risk of serious heart events if they do not have lipid-rich plaques, and this benefit only occurs in those with this specific plaque type.

See the scientific wording

Among patients with coronary artery disease, achieving an LDL-C level below 55 mg/dL does not significantly reduce the risk of major adverse cardiac events in those without lipid-rich plaques (maxLCBI4mm <324.7), suggesting that the benefit of intensive lipid-lowering may be limited to patients with this specific plaque phenotype.

Why this might work

When cholesterol levels in the blood drop very low, fatty plaques filled with cholesterol and immune cells shrink and become harder and less likely to burst. This only happens in plaques that are already full of fat and inflammation. In plaques without much fat, lowering cholesterol does not change their structure or risk of causing a heart attack.

  1. Study: Achieved LDL-C levels <55 mg/dL and cardiac events in patients and lesions harbouring lipid-rich plaque phenotypes

    For people with heart disease who don’t have fatty, unstable plaques, lowering LDL cholesterol below 55 mg/dL doesn’t seem to help prevent heart attacks or need for more procedures. But for those who do have these dangerous plaques, lowering LDL does help.
